Lb all whom it may concern:

Be it known that I, RALPH BAGGALEY, of Pittsburg, Allegheny county,Pennsylvania, have invented a new and useful Machine for StampingCopper, of which the following is a full and exact description,reference being had to the accompanying drawings, in Which Figure 1 is aplan view of the apparatus in its preferred form. Fig. 2 is a side view,partly in section. Fig. 3 shows a ratchetwheel and pawl for holding inposition the supporting-piece for the pig or other metal article to bestamped. Fig. 4 shows in crosssection a table with the supporting-blockfor the pig, together with the chute into which the pig is dumped afterstamping. Fig. 5 is a side view, partly in cross-section, of amodification in which mechanical pressure supplied by an eccentric,toggle-joint, or other device is substituted for the power-cylindershown in the other figures.

The object of my invention is to provide means for stampin weights,owners names, &c., on pigs or p ates of copper or other metalspractically Without hand labor, and I accomplish this result in mypreferred form of apparatus by means of hydraulic, steam, or airpressure and in my alternate form of apparatus by mechanical pressure,produced by a cam, eccentric, toggle-joint, or other device. In eachinstance I preferably arrange the die that carries the letters orfigures to be stamped so that when the latter have been forced into thepiece to the requisite depth a greatly-increased area ofdie-surface willbe brought into contact with the piece and will stop the travel of thedie. I may also supplement this by employing other stop mechanism.

. My present invention constitutes one of a series of inventions made byRalph Baggaley and E. W. Lindquist which make it possible to preparecopper pigs and plates for shipment more cheaply and expeditiously thanhas heretofore been possible.

In the drawings, 2 represents the table upon which the copper pig orother piece is dumped after it leaves the fin-trimming machinery andweighing-scales. It then rests upon a rotatable supporting-block 3,preferably of star shape, illustrated in cross-section in Fig. 4, whichis locked in position by locking mechanism 3, such as shown in Fig.

3. When in this position, it is in direct line or register with the dies4 5. (Shown in Fig. 2.) One of these dies is carried at the end of thepiston 6 of a cylinder 7, actuated by fluid, whether steam, air, orwater, and the other die is carried by a stem 8, which is movablelengthwise by a lever 9 and is backed by an adjustable eccentric stop10. Pressure is then applied to the cylinder, which causes the piston tomove the die forward and to engage the end of the pig, preferably on asunken rosette 11 thereon that has pre viously received a finishing cut.The endwise movement of the pig is limited by means of the resistancemechanism 10, so that when the limit is reached the pressure of the diel will sink the letters or figures into the finished rosette, and whenthey have been fully embedded the increased die-surface which thereuponengages the rosette effectually prevents further movement of the pistonand the die. When the stamping operation is finished, thesupporting-block is turned by a handle 12, Fig. 2, and the metal pig isdischarged into a chute 13, Fig. 2, along which it travels to a conveyeror other mechanism for storing it or delivering it for shipment.

The stamping mechanism shown in Fig. 5 is similar to that abovedescribed except in the means for applying and resisting the pressure.In this machine the die 4 is actuated by an eccentric 14, which may bereplaced by a toggle-joint or other device. Owing to possibly varyinglengths of the pigs or plates into which the metal is cast, and owingalso to the rigid movement of the camactuated machine, I provide a heavyspring 15 to bear against the die 5, and thus to receive and to resistthe pressure. The spring is capable of adjustment at will, and itsresistance to the pressure must be greater than the power necessary toembed the letters or figures in the piece. Any surplus movement of thedie 4 will therefore be absorbed by the spring.

Doubtless many variations in the arrangement of the details of thisapparatus will suggest themselves to those skilled in the art withoutdeparting from the spirit of my invention, since What I claim is 1.Apparatus for stamping, comprising a die and means for moving it, anopposite resistance-piece, and a rotatable support for the article to bestamped; substantially as In testimony whereof I have hereunto setdescribed. my hand.
